Subject AssertionError
Date Mon, 16 May 2011 15:07:11 GMT
Environment : java 64 bit server, java client, thrift get_slice method,
Cassandra 0.7.4, single node

Depending on the data I pass for a query on a CF I get the following
listed below. Any suggestions what could be wrong based on the stack
trace?
